Precision Universal Joints

The 'JXL' range of resilient couplings is able to accept angular, radial and axial misalignment, they are torsionally resilient, non-lubricating and capable of operating between temperatures of –50°C and +105°C.

The elements are flame resistant, anti-static and have NCB acceptance for use underground in coal mines number A2032.

All ATEX compliant 'JXL' anti-static / flameproof couplings are capable of accepting a momentary overload of twice nominal torque.

Couplings are selected on their ability to transmit torque between rotating shafts, with restricting factors being maximum speed and shaft diameter. (See selection notes below).

Supplied in either shaft to shaft version or flange to shaft for drives that require a flywheel connection. Flanges or hubs can be supplied in carbon steel, stainless steel and other exotic materials.

Torque in Nm = Power (Kw) x 9550
Speed (RPM)


example
‍
18.5 kW at 1500 rpm
‍
18.5 x 9550 = 117.783 Nm
1500


Calculate the torque to be transmitted, determine the required service factor with reference to the duty factor chart, multiply the relevant duty factors together to give the required service factor, multiply the calculated torque by this factor to give the required coupling rating. Select the coupling size with reference to the continuous value, taking into account the bore diameters required.
